MUSIC-LEAF TURNER.

T 0 aZZ whom it may concern Be it known that I, WILLARD L. STRONG, a citizen of the United States, residing at La Center, in the county of Clarke and State of Washington, have invented a new and useful MusioLeaf Turner; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

his invention relates to a new and use ful leaf turner, designed more especially for turning the leaves of sheet music, but which may also be employed for turning the leaves of books or other sheets.

The main object of the invention is to provide an improved device of this nature. which is simple and practicable in construction, and etficient in use.

The drawings disclose only one form of the present invention, but in practical fields this fori'n may require alterations, to which the applicant is entitled, provided the alterations are comprehended within the scope of what is claimed.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings:Figure 1 is a view in elevation. of a music leaf turner, constructed in accordance wit-h the invention. Fig. 2 is a longitudinal sectional view through the base of the turner. Fig. 3 is a transverse sectional view on line 3 3 of Fig. 2, showing the shaft bearing in section, and the gears 5, 8, 10, and the shaft 9 in elevation. Fig. -i is a sectional view on line 4.i of Fig. 2. Fig. 5 is a view in end elevation.

Referring more especially to the drawings accompanying this application 1 designates a hollow base, on the upper surface of which at each end thereof is a standard 2. Ar ranged on the interior of the base, substantially at its center portion is a socket 3, in which the shaft or red 4 is mounted. Movable with the rod 4 is a pinion with which the rack 6 meshes. Surrounding the shaft 4 is a tubular member 7, on the lower end of which a pinion S is keyed. A second tubular member 9 surrounds the tubular member 7. Fixed to move with the tubular member 9 Specification of Letters Patent.

at its lower end is a pinion 10. Arranges on the interior of the base are guide bracke The guide brackets 11 receive the rack bar 6, while the brackets 12 receive a slide bar 13. This slide bar 1.3 comprises two parts 14 and 15, which are provi l with rack teeth 16 and 17. The parts or portions 14 and 15 are off-set from one another, in other words, one above and one below, and arranged in alinement with the pinions 8 and 10, so as to operate them, when the slide bar is reciprocatcd. The parts or portions 14 and 15 are not only arranged one above and one below, but are so arranged. that the teeth 17 will operate the pinion 8 first, while the teeth 16 will subsequently operate the pinion 10, so that one leaf or sheet of music may be turned at a time. Projecting at right angles to the slide bar 13 and integral therewith is an arm 18, which projects through a slot 19 of the base. his a in 12 has an arm 20 pivoted thereto, and terminates in an extension arm 21. The arm 20 is used as a handle, while the extension arm 21 engages that which the base rests upon, thus constituting means to assist in supporting the base. The slot 19 is provided with a. projection 22, with which the arm 20 which is pivoted to the arm 18 contacts, thus limiting the slide bar in its sliding movement, so that only the second sheet 23 may be turned, without disturbing the third sheet 24 of the music. hen it is desired to turn the sheet 24, the arm 20 is raised so as to slide on the projection 22, thus allowing the slide bar 13 to be further moved, so as to cause the teeth 16 to operate the pinion 10. As the pivoted arm 20 slides on the projection 22, when the pinion 10 is being operated, the arm 18 slides under the projection 22. The rod or shaft 4, and the tubular members 7 and 9 are arranged telescopically with relation to one another, and the rod or shaft 4 projects beyond the upper end of the tubular member 7, and is provided with an arm 25 having a clamp 26, while the tubular member 7 projects beyond the tubular member 9 and is provided with an arm 27, which is also provided with a clamp 28. The upper end of the tubular member 9 (which is below the upper end of the tubular member 7 is provided with an arm 29 having a clamp 30. The arm 25 normally engages the upper end of the standard 2 on the left end of the base, while the arms 27 and 29 engage the upper end of the standard 2 on the right hand end of the base.

In operation a folder of music is so 'a-nged that the first sheet is engaged by the clamp 26 shown at the left in Fig. 1, while the second and third sheets 23 and 24: are engaged by the clamps 28 and 30. These clamps are of the usual construction,therefore the same are not shown in detail. lVhen the folder of music is so arranged, and it is desired to turn the leaf 23, the slide bar 13 is reciprocated thus causing the teeth 17 to mesh with the pinion S which in turn will rot-ate the tubular member 7, thus throwing the arm 27 over in contact with the standard 2 on the left hand of the base. then the arm 27 is thus moved the leaf 28 is also turned. lhe slide bar 13 when so moved is limited by the arm 20 which is pivoted to the arm 18, coming in contact with the projection 22. When it is desired to turn the sheet 24!; the arm 20 is lifted to slide on the projection 22. To reset the leaves to the position shown in Fig. 1 the rack bar 6 is moved in the direction of the arrow 31, by taking hold of the handle which is connected to the bar 6 and projects through a slot 83 of the base, and by moving the rack bar (3 in this direction, the pinion 5 is rotated, and with it the shaft or rod 4. When the shaft or rod l is so rotated, the arm 25 is thrown over against the standard 2 on the right hand end of the base, which also returns the arms 27 and 29 to the position shown in Fig. 1 and when so returned the slide bar 13 is returned to its normal position by the pinions 8 and 10.

The invention having been set forth, what is claimed as new and useful is In combination, a base having a plurality of telescopically arranged partially rotatable members having leaf turning arms mounted in bearings of the base, three pinions one carried by each rotatable member, a slide bar having two sets of rack teeth, one in advance and below the other, adapted to first rotate one pinion and its rotatable member and upon further sliding movement, the second pinion and its rotatable member, a rack bar to be operated in the opposite direction to rotate the third pinion and its rotatable member for resetting the members through the cooperation of the leaf-turning arms, the base having an elongated slotprovided with a member extending half the length of the slot, the slide bar having a projection extending through the slot for moving the bar to impart movement to the pinions, the projection having an arm pivoted thereto and adapted to contact with the member of the slot to limit the slide bar substantially mid-way of its entire movement, the pivoted arm of the projection being adapted to be raised to move on the member of the slot to complete the entire movement of the slide bar.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
